Cobblestone Generator Tweak
Cobblestone Generator Tweak changes what a cobblestone generator produces, with stone, andesite, diorite, gravel and ore variants defined in datapacks.
What it does
Standard cobblestone generators no longer give only cobblestone. The mod tweaks them so they produce several stone types, and in some cases rare ores, with the odds balanced to keep progression close to vanilla. Generators are defined by datapacks, so a server owner can add a custom generator without changing any code. A preset collection of generators comes bundled, so the mod functions straight after installation with no settings to change.
Each generator type is set by a block placed under a hopper, under a normal piston, or under a sticky piston with glass above it. Some generators need two defining blocks, and both must be present for the generator to work. A regular cobblestone generator still produces the first block, and the block under the generated cobblestone can be replaced with the one the player wants to use.
The mod is server-side only, so players join without installing it. It runs in singleplayer and multiplayer with no special setup beyond the datapack. Files are published for Fabric, Forge and NeoForge, all for 1.21.1, with 1.1.0 as the latest file. The code is not open source: All rights reserved applies.
Key features
Varied stone output
Generators produce stone, andesite, diorite, gravel, mossy cobblestone and sandstone, not only cobblestone.
Ore generators
Coal, copper, lapis and redstone ores, including deepslate variants, can come from generators as well.
Datapack-driven generators
Each generator is a JSON file in a datapack, so new generator types can be added without touching code.
Hopper, piston and sticky piston setups
Generator types depend on the block under a hopper, the block under a piston, or the glass block above a sticky piston.

What the author says
Tired of your cobblestone generator always giving the same block? This mod tweaks it so generators can produce various stone types and even rare ores. It works very simply: start by building a regular cobblestone generator and let it produce its first block. Then, replace the block under the generated cobblestone…
